Study Notes
Functional Anatomy of the Brain and Spinal Cord
- The frontal lobe is important for motor control and involved in motor aspects of speech, planning, abstract thinking, and social behavior.
- The parietal lobe is responsible for perception of touch, temperature, vibration, and proprioception, as well as memory and abstract reasoning.
- The temporal lobe is involved in hearing, scent, taste, recognition of speech, and memory, in cooperation with the limbic structures.
- The occipital lobe is responsible for vision and relates visual stimuli to "actual things," as well as storing memories related to what has been seen.
- Memory formation requires attention and structures that process and form new memories, with attention linked to the prefrontal lobe and memory "processors" to the structures of the limbic lobe.
- The basal ganglia, located below the cortex, regulate behaviors and movements and are impaired in diseases causing tremors, rigidity, and difficulty initiating movements.
- The basal ganglia includes structures like the striatum, globus pallidus, and subthalamic nuclei, while limbic structures like the amygdala and hippocampus are also present.
- The thalamus relays information from sensory receptors to the cortex, while the hypothalamus controls the endocrine system, regulates temperature, and modulates emotion and memory formation.
- The cerebellum, comprising about 10% of brain mass, compares information from receptors to adjust movements and error-corrects planned movements.
- The brainstem, composed of the midbrain, pons, and medulla, is responsible for various functions, including housing cranial nerve nuclei and pathways for sensory and motor information.
- The spinal cord, isolated from the peripheral nervous system, has gray matter with cell bodies and white matter with myelinated axons, divided into dorsal, lateral, and ventral columns.
- The spinal cord's gray matter includes dorsal horns for sensory information transmission to the brain, while the white matter consists of myelinated axons without cell bodies.
